Resource Grid(s) for Multiple Numerologies

The Resource Grid table is used to configure the Resource Grid(s) for each numerology. Numerology must be set to Multiple Numerologies for the Resource Grid(s) tab to appear. The N_grid_start column values correspond to the unusable RB (gray in the image below), N_grid_size column values correspond to the usable RB (light blue in the image below), and k0 is automatically calculated based on the formula in 5.3.1 of latest 38.21. All the enabled numerologies are aligned at point A.

Click Minimize k0 offset to limit k0 to the range of [-6, 6] to have all the usable RB almost in the middle of the carrier. The graphical display for the whole Radio Frame is located at the bottom part under the Carrier node. It displays the resource allocation for each channel in time/frequency two-dimensional resource grid. The X-axis represents the slot based on the current numerology and Y-axis represents the RB value. Each channel in the graphical display uses the same color as its channel block.
